Is it normal to estrange yourself from your family?

So my mom is alcoholic and coke head. I haven't seen or talked to her for two years and before that it was four years. She tries to talk to me but I ignore her. She tried to give me Christmas and birthday presents for the past few months but I never told her my address. I don't like her. I don't think I even love her. I used to want to use her for stuff, money and electronics. Now I just ignore her.

My aunt and uncle raised me for a few years. They are the only family members I feel LIKE I love. I'm not sure if I'm capable of love. I don't talk to them anymore either. It's been about five years since I spoke to them. It really bothers me that I don't see them but they live in Jersey and I'm in North Carolina.

My dad, who is my adopted step father, used to be my idol. I used to love visiting him, going fishing with him, doing anything with him. But ever since he got custody of me, we started having problems. We argued and couldn't stand each other. We started hating our company and avoided each other. I think part of the reason for this animosity is that we moved to NC to take care of my retarded aunts and that caused extra stress to me and him. I haven't spoken to him since he kicked me out almost a year vago.

So, that should be enough info. Oh, he kicked me out since I didn't like setting up direct deposit to his account.
